Abstract:
Speech features were perceptually analyzed in two groups of children. The first group (n = 6) had undergone cerebellar tumor resection, and the second group (n = 6) included children with brainstem tumors. Children belonging to the first group became dysarthric after a postoperative mute phase. Slow speech rate was a specific feature, but scanning speech and irregular articulatory breakdown (i.e., prominent characteristics in adult ataxic dysarthria) were not observed. In the second group, hypernasality was a prominent characteristic and resembled flaccid dysarthria in adults. These findings suggest that acquired childhood dysarthria needs a proper classification.
